specification of Letters Patent. Patented Feb, 27, 1917,

Application mea April 25, 1914. serial No. 834,512.

To all 'whom z't may concern:

Be it known that I, CHARLES; J. DUDLEY, a citizen of the United States,residing at North Tonawanda, in the county of iagara and State of NewYork, have invented certain new and useful Improvements 1n appendedValves, of which the following is a. specification, reference being hadtherein to the accompanying drawing.

'This invention relates to valve structures and appertains to that classthereof which are utilized in connection with steam radiators.

The primary object of the invention is to provide a valve of the kindspecified wherein the co-acting parts are so aggrouped and related thatthe quantity of the passing fluid, etc., may be accuratelypredetermined.

It is a further object of my invention to provide an eflicient form ofvalve that is simple in design and construction and in which Atheessential instrumentalities provided are so aggrouped that certain ofthese are replaceable for purposes which will hereinafter be set forth.

The invention in genera-l seeks to provide a valve structure which, asalready specified, is particularly adapted for use in connection withsteam radiators and which structure from an operative standpoint, willin practical use possess a high degree of eiiiciency and durability.

Other objects and advantages will in part be obvious from the annexeddrawings and will also be in part pointed out in the followingdescription.

The invention resides broadly in the features of construction,combinations of elements, and arrangements of parts, andvin variousaggroupments thereof, all as will be exemplified in the constructionhereinafter set forth, and the scope of application of which will beindicated in the claims hereto appended.

In order that this invention may be clearly comprehended by thoseskilled in the art, drawings illustrative of one of the many possibleembodiments of the same are hereto as a part of this specification; itbeing manifest that othervpossible embodiments employing the underlyingprinciples of my invention fall within the spirit thereof and within theobjects contemplated thereby.

In these drawings:

Figure l is a view in vertical section of a valve-structure embodyingmy" invention, the. parts being in such position that the valve isclosed;

Fig. 2 1s a fragmentary view, vin vertical section, showing the valveopen;

Fig. 3 is a view in horizontal section, on the line 3 3, Fig. 2, thesplit-ring being shown, in this instance, as having been turned somewhatto bring its ends into view, similarly as in Fig. 2;

Fig. 4 is a fragmentary view in elevation looking into one of theopenings in the valve-body;

Fig. 5 is a collective view of the insert member, in elevation and invertical and horizontal section, respectively; and

Fig. 6 is a similar view of the split member-retaining ring.

Referring to the drawings, the referencecharacter l designates a casingwhich obviously may be of any preferred form and construction, providedthat it includes an inlet port 2 and an outlet port 3. In this instance,the outlet port is formed in the tubular portion 4 arranged at an angleto the casing, and which is in communication, through said outlet port 3and an opening 20, with a chamber', on the interior of the casing.

Upon the outside of said casing, at its upper portion, there is provideda circumferential enlargement or flange 6 which may be graduated orotherwise marked, for a purpose presently to be explained. This casing`etc., constitutes one component of the valve structure.

The casing is, preferably and as shown,

a valve stem 12 which is provided with screw threads 13 adapted toengage the inner threads 9 in the sleeve 8. The stem, at its lower end,carries a head or enlargement 14 provided with an annular recess 15.--The head and the stem on which it is formed-v constitute one'of theactive means for controlling the passage of steam or the like throughthe outlet and, according to itsparticular position therein, operates toclose said port entirely, or to open it to varying degrees.

The, stem is rotated manually, and this operation is facilitated by thehand-piece 16, which is preferably detachably secured to the upper endof the stem, as shown.

Also secured to the stem, in any preferred manner, is a pendent' collar17, the lower portion of which occupies an annular recess 18 formedbetween .the upper end of the sleeve 8 and the casing. Mounted upon thiscollar is an indicator extension 19 adapted to overlie the graduatediange 6, as shown in Fig. 1, and to coperate with graduations thereon(not shown) to indicate to the operator the relative position ofthefluid-controlling instrumentalities.`

As shown in Figs. 1, 2 and 3, the portion 4 of thecasing isprovided withan opening 20 of a vertical dimension less than the vertical dimensiono-f the stem-carried head 14. Seated in this opening is a reducerelement l or flow-determining member 21 comprising *a disk portion 22and two rearwardly-eX-I ltending portions 23, between vwhich there isformed, in the disk, an opening 24 which, in:` this instance, is shownas rectangular, though it may be of any other desired or required form.The disk portion of the element occupies an operative position in arecess 25 formed in the vertical wall of the portion 4. Therearwardly=extending por- I l tions 23 project through .the opening 20and beyond the exterior plane of the head 14. To this end,the portions23 are cut on an arc so thatthe curved edges thereof' embrace theperiphery of the head 14. Any suitable means may be provided forretaining the reducer element 21 in operative positio'n. In thisinstance, I have shown, as an example of such means, a resilient member26, in the form of a split-ring. The ringis adapted to be sprung intoa'groove 27 vformed in the portion 4 of the casing. When the head 14 isin its lowermost position, it abuts against a flange 28 formed in thecasing'and, when in this position, said head entirely closes thevopening 24, as shown in Fig. 1. -When the stem is manipulated to elevatethe head away from the flange 28, it will, in progressive degrees,permit a flow of Huid between the portions 23 and through the opening 24of the reducer element and out through the outlet port 3. The preferreduppermost position of the head is illustrated may be a series of thesereducer elements provided with differently-sized openings to accord topredetermined calculations, whereby a predetermined'quantity of steammay pass therethrough. In other words, their size bears a definite ratioto the normal pressure of the steam and the volume and size of theradiator to be supplied; that is to say, if the size be, say, 60 sq.ft., the opening 24 will be cut so that no more steam, under a iveouncepressure, (say) can pass through the valve and into the radiator thanwill fill, for instance, a sixty-foot radiator up to 85% of its capacityor volume. Thus, it will be seen,no steam can be wasted, since less thanthe maximum capacity of the radiator is provided and, in this way,over-heating of the radiator and waste of steam are avoided.

From the foregoing it will be perceived that I have succeeded indevising a valvestructure which is well adapted to achieve the severalobjects and ends in view. The structure is compact in form, ischaracterized by simplicity, and the parts are so formed and constructedas to permit of its ready application.

As many changes may be made in the construction herein disclosed andmany widely different embodiments of the invention can be made withoutdeparting from the spirit thereof, it is intended that all mattercontained in the foregoing description and shown in the accompanyingdrawings shall be interpreted as illustrative and not in any limitingsense.

It is also to be understood that the language used in the followingclaims is intended to cover all of the generic and speciic features ofthe invention which, as a matter of language, might be said to falltherebetween.
